- 1/2 cup chopped green onions
- 2 cloves garlic, minced
Dairy and Cheese
- 1 cup shredded cheddar cheese
- 1/2 cup cream cheese, softened
- 1/2 cup heavy cream
- 1/4 cup grated Parmesan cheese
Seasonings
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Instructions
- Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish to ensure the casserole doesn’t stick during baking.
- Sauté Aromatics: In a large skillet over medium heat, sauté the minced garlic and chopped green onions until fragrant, about 2 minutes. This releases their flavors and softens them slightly.
- Cook Cauliflower Rice: Add the cauliflower rice to the skillet and cook for 5 minutes, stirring occasionally, until it becomes slightly tender but not mushy, which maintains a good texture in the casserole.
- Combine Ingredients: In a large bowl, mix together the cooked shredded chicken, sautéed cauliflower rice mixture, softened cream cheese, heavy cream, half of the shredded cheddar cheese, grated Parmesan cheese, salt, and black pepper. Stir until all ingredients are well combined into a creamy mixture.
- Assemble Casserole: Transfer the combined mixture into the prepared casserole dish, spreading it evenly. Sprinkle the remaining half of the shredded cheddar cheese over the top to create a cheesy crust once baked.
- Bake: Place the casserole dish in the preheated oven and bake for 25 to 30 minutes, until the casserole is bubbly and the cheese topping has melted and turned golden brown.
- Cool and Serve: Remove from the oven and let the casserole cool for a few minutes to allow it to set slightly, making it easier to serve.
Notes
- For extra flavor, you can add herbs like thyme or rosemary to the mixture before baking.
- Use pre-cooked rotisserie chicken to save time.
- If you prefer a lower-fat version, substitute heavy cream with half-and-half and use reduced-fat cheeses.
- Cauliflower rice can be fresh or frozen; if frozen, make sure to thaw and drain excess moisture before cooking.
- For a spicier version, add some crushed red pepper flakes when sautéing the garlic and onions.
